TROUBLESHOOTING
-Primary Test: Is the shutter positioned properly? A mechanical shutter is used to block the internal gate, switching the device to laser gate mode.
-Secondary Test: Connect the photogate to a LabPro and run the data collection program. On the main screen, confirm that blocking and unblocking the gate is working OK by using your hand to block the gate.
-If the photogate is not working with your picket fence, make sure that the protective plastic covering the picket fence has been removed.
